Hi and thank you for using pet coach! Below you will find a link for the American College of Veterinary Surgeons, a very reputable website where you can find the most accurate and up to date information on many things including osteosarcoma. The carpal issues you see in your dog is what is known as carpal valgus. This does not predispose to osteosarcoma formation and in Brunos case I would say that it is not bad enough to require surgery unless it is causing an obvious lameness. Surgical correction is the treatment for valgus deformity. I hope this helps! Please let me know if you have any other questions or concerns. https://www.acvs.org/small-animal/bone-tumors
